What size are my wheels?

I have a wheel off of a early 70's italian road bike. They are tubulars. What size will this be? Is there a good way to measure?

Yes, look for markings on the rim.

Where would I look for such markings? There are no stickers on the rims themselves.

They've got to be 700c. A 27" tubular was never made, even though some of them were labled 27". I doubt if you'd find one of the oddball sizes on a '70s Italian roadbike.

Is this a sarcastic post meaning I should have known this information? Or are you asking my question back to me?

Usually stamped, near the valve stem hole would be my guess. 700c sounds right... unless you've got 650's.


Got a picture?

Not right now. When I get home tonight I'll snap a couple of pics.

You're not likely to find stamping on tubular rims, just labels, because the metal is thin. Even the labels may not state the size, just brand and model. Sheldon Brown's site http://sheldonbrown.com/rim-sizing.html requires you to measure the "bead seat diameter", more applicable to clinchers, but a 700c tubular is approximately 24-3/4" diameter at the edge.

If it's a normal-sized bike they'e
"normal" tubulars, also sometimes known as "700" and also sometimes, inaccurately, described as either "27 inch" or "28 inch."

Tubular sizing is MUCH less of an issue than clincher sizing, unless you get involved with models for very small adults ("26 inch") or children (24", 22", 20") All of those sizes are super rare.

the 27", and the 28" tubulars are usually Continentals. Most everyone else calls 'em 700c. Regardless of what the manufacturer says, they were all 700c (excluding sheldon's references to the smaller "juniori" tires (btw, I have a 24" somewhere if someone needs one for their micro world champion...)

Sorry to bring this tread back up but I just want to clarify: if I have a tubular tire that says 700c on it, it can be replaced with a tire labeled, for example, 28x22?

For example this one: http://www.probikekit.com/display.php?code=Y1345

Thanks!
